TEST BENCH FOR INVESTIGATING EFFECT OF VARIABLE LOADING OF ROCKS ON FLUID FILTRATION Russian patent published in 2025 - IPC G01N15/08 

FIELD: measuring.

SUBSTANCE: invention can be used to study the effect of acoustic vibrations on permeability of rock samples. Proposed device comprises core holder with rubber collar and rock sample, thermal cabinet, providing maintenance of constant temperature of fluid and rock sample, two-cylinder pump providing fluid supply to the core holder at constant flow rate or constant pressure, differential low and high pressure sensors, back pressure regulator, which controls back pressure in the system during research in non-stationary conditions at formation pressure and temperature, crimping pressure generating system to provide formation pressure in the sample, accumulators with working fluids, pipeline system, providing supply and output of working fluids, measuring flask with weights, for determining the amount of liquid released from the core holder, receiving chamber connected to the core holder, which is a hollow cone-shaped part having two nozzles, wherein at the end of the chamber there is a sealing cover on which a Langevin emitter is screwed, which is connected by wires to a signal generator.

EFFECT: providing the possibility to carry out research on determination of permeability under action of acoustic vibrations in conditions close to reservoir ones.
